PROBLEM TO BE SOLVED: To provide fittings hardly causing a warp of a panel body. SOLUTION: In a door panel 20, an adhesive margin with an indoor side metallic face material 26 of a stile 23 arranged in the thewrmally extending direction is remarkably reduced more than a contact margin with an outdoor side metallic face material 25 to thereby reduce drag received from the indoor side metallic face material 26 with little thermal expansion, and since the thermal expansion of the stile 23 is not restricted so much, the whole stile 23 uniformly extends by following the thermal expansion of the indoor side metallic face material 25, and hardly warps. Thus, the warp of the whole door panel 20 can be effectively restrained, and clearance is generated between a door frame 10 and the door panel 20 so that a dead bolt of a lock set 29 and a locking metal fitting for locking can be made to function surely.
